盘谷寺-新乡断裂第四纪活动性分段特征

盘谷寺-新乡断裂以柏山、高村为界，分为西、中、东3段，根据物探剖面、地质标准孔和地层剖面出露特征，各段活动性具有明显差异。其中西段最新活动时代为中更新世，具有向盆地迁移发育的特征；中段最新活动时代为晚更新世早期；东段活动性稍复杂，经历了正断-逆冲-正断的运动过程演变，其最新活动时代为晚更新世早期，且活动强度向两端减弱。高村所处的武陟隆起区推测为盘谷寺-新乡断裂中、东段的挤压阶区，断层位移在此处有亏损和衰减。

Quaternary Active Segmentation Characteristics of the Pangusi-Xinxiang Fault

The Pangusi-Xinxiang fault is divided into three sections, western, middle, and eastern, bounded by Baishan and Gaocun. According to the exposed characteristics of geophysical profiles, geological standard holes and stratigraphic profiles, the activities of each section are significantly different. Among them, the latest active age of the western segment is Middle Pleistocene, which has the characteristics of migration and development to the basin; the latest active age of the middle segment is the early late Pleistocene. The eastern segment of the fault has slightly complicated activity, and it has undergone the evolution of normal fault-thrust-normal faut, the latest activity age is early Late Pleistocene, and the activity gradually decreases towards both ends. The Wuzhi uplift area where Gaocun is located is presumed to be the compressional terrace of the middle and eastern segments of the Pangusi-Xinxiang fault, where the fault displacement is both depleted and attenuated.
